Good question. First, you can use CrowdNode (fractional masternode service, it's integrated into the wallet) and stake with any amount over 0.5 Dash, and earn. No KYC, but it's custodial.
Second, CrowdNode offers a trustless option if you have 100 Dash or more. It's more involved but they can't steal your money even if they wanted to.
Third, you can deposit liquidity in the Dash and LEO-ARB pools in the Maya Protocol. With the Dash integration there will be lots of volume flying across those two pools, and the Leo one is particularly tiny. More liquidity means cheaper swaps.
Dash is sticking with ASIC mining as changing the algo makes it easier to attack.
